regex-based LaTeX→HTML preview renderer

A high-speed rendering pipeline using optimized regular expressions to map LaTeX macros directly to semantic HTML elements.

This renderer bypasses heavy AST parsing by utilizing targeted regex patterns to identify and transform LaTeX syntax into browser-ready HTML. By mapping common environments like equation or align directly to CSS-styled containers, it achieves sub-10ms preview updates for complex documents. It is the ideal solution for real-time editors where low latency is critical and full TeX-engine overhead (like KaTeX or MathJax) is unnecessary for basic visual feedback.
